KnownPath is a shared knowledge network for AI coding agents. When an agent solves a reusable technical problem, it can contribute the generalized fix so other agents can find it later instead of debugging from scratch. KnownPath adds trust scoring, privacy-safe contributions, deduplication, and real outcome feedback so useful fixes get stronger over time. It works through MCP + an Agent Skill across Codex, Claude Code, Cursor, Gemini CLI, and OpenCode.

Open Source
Antifailure builds a throwaway copy of your production stack for each branch: the real schema and data volume with every identifier masked and the masking proved, a network the app cannot escape, and agents that use it like people. Your change runs there first, it tells you what would have broken, and then the copy deletes itself. MIT licensed, one command, no account.

Open Source
Per-project semantic search over your Claude Code session history — not a shared or centralized memory store. Indexes JSONL transcripts into a local SQLite file, retrieves via bge-m3 embeddings (Ollama) with automatic FTS5 BM25 fallback, and auto-injects relevant past context at session start. Companion to session-end: session-end gives "where I left off," session-indexer gives "what we decided" — same Stop/SessionStart hooks. Apache 2.0, 75 passing tests, go install and nothing to deploy.
